Answer 1

Hello!

We have a table with size 3x3, right?

So, our matrix W will have the same order, look:

`W=\begin{bmatrix}{w_(11)} & w_(12){} & {w_(13)} \\ {w_(21)} & {w_(22)} & {w_(23)} \\ {w_(31)} & w_(32) & w_(33)\end{bmatrix}`

Knowing it, let's write the matrix with the values contained in the table:

`W=\begin{bmatrix}{28} & {21} & {19} \\ {17} & {24} & {15} \\ {22} & {29} & {17}\end{bmatrix}`

According to the explanation, the element w31 will be 22.
